Hi again Ian !!...

Have tried this....but, as reported, there are no relevant settings to tweak !..
Have finally found someone on the Advent Forum who appears to have some impression as to what is what...but as yet he seems to be as baffled as you, I, and 'Restless'....
will keep you posted !!.. Thanks... Alan.A
